Abstract
A data processing device includes an instruction decoder and an arithmetic logic unit having first and second inputs and an output. An accumulator is connected between the output and first input of the arithmetic logic unit. A further register is connected between the accumulator and the second input of the arithmetic logic unit. The arithmetic logic unit includes circuitry for computing a digital value to the accumulator as well as an additional circuit. The additional circuit thereupon compares the value at the second input from said register with the digital value in the accumulator in response to a command from the instruction decoder and then stores to the register the lesser or the greater in value of the contents of the register and the digital value in the accumulator depending on the command. Other devices, systems and methods are also disclosed.
